JOHN CUNNINGHAM, OF CINCINNATI, OHIO.

HOG-HOIST.

SPECIFICATION forming part of Letters Patent No. 256,200, dated April 11,1882.

Application filed January 23, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN CUNNINGHAM, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in. Hog-Hoists, which improvement is fully set forth in the following specification and accompanying drawings, in which-- Figure 1 is a side elevation of the hoist, and Fig. 2 is a top view of the same.

The object of my invention is to provide a hog-hoisting device.

By reference to the accompanyingdrawings, A represents the joists of a building, and B B posts to which the hoist is attached. 0 is a cross-shaft journaled to the hangers C. This shaft centrally carries a spool, D, and near one end a pulley, E. The opposite end ofthe shaft has apulley, E, to receive the power from the engine.

F is a shaft parallel tothe shaft C, journaled at one end to the hanger F a short distance from shaft C. The opposite end of the shaft F is journaled to a vertical lever, G, the upper end of this lever being hinged to the joist or upper frame-work of the device. The shaft F carries a pulley, H, on a line with pulley E of shalt Cyand at a point near the vertical lever G is a small friction-pulley, H.

Parallel and near to the shaft F is another shaft, I, journaled to the hangers I. This shaft carries centrally a friction-pulley, J, which shaft F. On the shaft I is also a drum, K, to receivea coil of rope, as will be hereinafter shown. Motion is transmitted from pulley E to pulley H by means of the wire rope or belt L.

Beneath the shafting here described is a beam, M, hinged at its rear end to a post at M. This is so located in position that it is directly under the large friction-pulley J on the shaft 1, and the upper side of the beam has a circular depression cut into it, so as to fit the friction-pulley. The forward end of the hinged beam M is provided with a downwardly-projecting arm, 0, whose lower end is hinged to a centrally-pivoted lever, P, which carries on its opposite end the wheel Q, the object of which will be explained.

R is a cross-beam below and at right angles with direction of the hinged. beam M. To the forward side of the beam is attached the track S, on which the slaughtered hogs are conveyed to the scalding-vats. On the rear side of this cross-beam R is astaple, T. A rope, U, secured to the lower end of the lever G, passes through the staple T, thence up and around to the spool D on the shaft C, and forward to the pulleyblock V'. The drum K on the shaft I has a rope, W, around the same, the opposite end of which passes forward to the pulley-block X, thence down through the hinged beam M, and has the hog-hook Y attached to the lower end. A knot or weight, Y, is formed in the rope W a suitable distance above the hook Y.

The operation of the hoist is as follows: The hog is caught and secured to the hook Y, as is ordinarily the case with the common hoist. The rope U is then drawir forward in the direction of the arrow Z. This causes the rope to bind on the spool D and draw the rope through the staple T, bringing forward the lower end of the lever Cr. The inner end of the shaft F being journaled to the lever, the friction-wheel on this shaft is pressed against the large friction-wheel on shaft J. This causes the shaft I and drum Kto revolve, winding up the rope W and suspending the hog. When the-rope W has been drawn up to that point where the weight or stop Y touches the lower edge of the beam M the beam is also elevated to the point shown by dotted lines Z.

t The depression N at this point strikes the friction-wheel J, checking its motion. At the same time the arm 0 on the edge of the beam M has tilted the lever P toward the rope W, causing the wheel Q to press the rope W toward the track-rod S, enabling the hook Y to be readily attached to the said track-rod S. When, now, the friction-pulley H is removed from the pulley J, the weight of beam will be sufficient to return it to its original position, and the hog having been transferred from the hook to the rod-track S, the weight Y and the hook Y will be sufficient to unwind the rope from the drum K, so that it may be lowered to receive another animal.

Two or more devices may be placed side by side, all working from the same line of machinery.

Having described my invention, what I claim is- 1. In an animal-hoist, the hinged beam M, adapted to check the friction-pulley J, in combination with the friction-pulley J, rope W, having the animal-hook Y, and provided with the knot or stop Y for raising the beam M, substantially as herein set forth.

2. In an animal-hoist, the shaft (3, having the pulleyE and spool D, in combination with shaft F, having the pulley H and journaled to the swinging lever Gr, and with rope or belt L 4 and rope U, substantially as and for the purpose set forth.

3. In an animal-hoist, the hinged bean-1 M,
